Ostrow Mazowiecka uprising

The Ostrow Mazowiecka uprising occurred from 15 to 18 February 1943 when Polish partisans rose up in Ostrow Mazowiecka in eastern Poland (then part of the German General Government). The partisans were trained by the United Kingdom, and they likely belonged to the experienced Home Army, as their 9,000 troops were arranged in a division-like style. The German Wehrmacht's German 154th Reserve Division crushed the uprising after leaving neighboring Warsaw, and the Polish partisans were forced to surrender. The uprising left 56 Germans and 62 Poles dead on the battlefield, and the Polish survivors were forced into concentration or extermination camps, with many being executed or worked to death.
